The biological effects of ultraviolet radiation (UVR) on the skin have been known for years, which is why there has been an increase in the use of sunscreen products, whose purpose is to protect the skin from these effects through the action of sunscreens that absorb, disperse, or reflect radiation.
Sunscreens contain sun filters that act to protect human skin from the harmful biological effects of UVR. However, due to problems related to the effectiveness and safety of sunscreens in recent years, we have resorted to the search for potential photoprotective molecules from natural sources, among which are marine macroalgae which in turn are a source of molecules with potential antiaging effects.
The present review shows the current state of sun filters, the mechanisms that trigger aging, and several compounds present in marine macroalgae with photoprotective and antiaging capacity with potential use in cosmetic products.
NAD+ levels decline as we age. There is some evidence from studies in model organisms that restoring NAD+ levels can increase lifespan/healthspan. One way to restore NAD+ levels is through NMN supplements, which is a precursor to NAD+. In this video, I will go into more detail regarding this and also look at why it could be beneficial and when are the potentially best times for NMN to be taken.
The cell senescence model of age-related disease provides a single framework for understanding many age-related diseases, specifically including the dementias, such as AD. It further suggests that such diseases may be both prevented and effectively treated through a gene-therapy intervention that is currently feasible and that will effectively test the cell senescence model.
16:8 intermittent fasting, which people sometimes call the 16:8 diet or 16:8 plan, is a popular type of fasting. People who follow this eating plan will fast for 16 hours a day and consume all of their calories during the remaining 8 hours.
Suggested benefits of the 16:8 plan include weight loss and fat loss, as well as the prevention of type 2 diabetes and other obesity-associated conditions.
The easiest way to follow the 16:8 diet is to choose a 16-hour fasting window that includes the time that a person spends sleeping.
Some experts advise finishing food consumption in the early evening, as metabolism slows down after this time. However, this is not feasible for everyone.
Some people may not be able to consume their evening meal until 7 p.m. or later. Even so, it is best to avoid food for 2–3 hours before bed.
People may choose one of the following 8-hour eating windows:
9 a.m. to 5 p.m.
10 a.m. to 6 p.m.
noon to 8 p.m.
Within this timeframe, people can eat their meals and snacks at convenient times. Eating regularly is important to prevent blood sugar peaks and dips and to avoid excessive hunger.
